Abstract:
This paper summarizes the occurrence, and damage
caused by, the seven migratory insect pests that are the most serious pests of
three major food crops in China. These pests are found throughout China's crop
planting areas and migrate to and from other countries. Techniques for
monitoring adult populations, using ovarian development to classify female
moths, wing type investigation and remote forecasting, are summarized. Accurate prediction of the occurrence of these pests requires development of an
integrated national ground and aerial monitoring network, the study of disaster
mechanisms, use of intelligent monitoring tools and the identification of
critical migration pathways.
